Yttriated Tungsten is primarily used in military and aviation industry with narrow arc beam, high compressing strength, highest welding penetration at medium and high current.
In some welding cases of high requirement to arc voltage and arc current, the usual wire feeding system is unable to meet the needs of wire feeding at present.
在一些对电弧电压、电弧电流要求很高的焊接场合，目前常用的送丝系统将难以满足要求。
